WebThe samples outside of the finite bounds of the given signal are x[n] = [0.5,-0.7,0.3,-0.2,1.5] a. Write the expression for the Discrete Fourier Transform (DFT) of the given signal as a function of discrete frequency Be sure to expand the summation over all n, but you DO NOT have to substitute the k values. WebMay 22, 2024 · In this module we will discuss the basic properties of the Discrete-Time Fourier Series. We will begin by refreshing your memory of our basic Fourier series equations: f[n] = N − 1 ∑ k = 0ckejω0kn. ck = 1 √NN − 1 ∑ n = 0f[n]e − (j2π Nkn) Let F( ⋅) denote the transformation from f[n] to the Fourier coefficients. F(f[n]) = ck, k ...
